PAUL R. SHAIIJER, OF WASHHVGTON, DISTRICT OF COLUMBIA.

HAND-CARRIED FLUORESCENT INDICATOR OR SIGNAL.

Application filed May 6,

To all whom it may concern:

Be it known that I, PAUL R. SHAILER, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Hand Carried Fluorescent Indicators or Signals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer ence being had to the accompanying drawings, and to the letters and figures of referwhich form a part of this specification.

The object of my invention is to provide a fluorescent indicator, and more especially a signal device which is particularly adapted for use by automobili'sts.

A further object of the invention is to pro vide a device of the character specified which is adapted for use on the hand of the operator.

Incidentally, by the use of a fluorescent indlcator I dispense with the use of the ordinary electric light bulb, carried on the hand of the operator in circuit with abattery car ried upon the body of the operator.

With these objects in view, the invention resides, generally stated, in the combination of a member having a surface suitablefor the reception and retention of a material havin fluorescent properties, and means connected with said member for securing the same conveniently to the hand of the operator.

The invention is clearly dlsclosed' in an exemplary form in the accompanying drawing, in -which like reference characters designate corresponding parts throughoutthe several views. Briefly described:

Figure 1 is a view in top plan of a device constructed in accordance with my invention in use on the hand ofan operator;

Figure 2 is a sectional view on the line 2, 2 of Flgure 1;

- Figure 3 is a perspective view. of the device of my invention lookingat the under side thereof, and

Figure 4 is a diagrammatic view illustratin the use of the invention.

' Iteferring now in deta l to the drawing:

1 designates a member, in this instance a I a plate, of angvpreferred shape, such as a disk as shown in lgure 1, or of ellip shown in Figures 3 and 4. Sand member is of any suitable material having a surface Specification of Letters Patent.

pound. Preferably, said fluorescent material is so disposed on the disk 1 as to leave a border 2. surrounding such fluorescent surface, which border may-be colored in any sultable manner, so as to constitute a signal which is adapted to be used during the day as well as at night. The fluorescent surface 3 may be protected, if desired, in any suitable manner, as by means of a disk 4 of appropriate material, such as celluloid, said disk bein retained in position beneath a lip 5 carried y a ring 6, secured to the disk 1 It is a well known law of physics that any article which is visible by external light and which is not reflective is a refracting surface. An object is visible onl by reason of certain rays being reflected, ut unless the surface is highly polished the reflection is only partial, other rays being refracted. An ordinary surface is, therefore, arefracting surface. The surface 3 of the present device refracts the light which implnges thereon. The refraction is further augmented by the curvature of the transparent member 4. This transparent member 4 is of necessity a reflecting surface. The device, therefore,

combines the properties of fluorescence, re-

flection and refraction.

The invention comprehends suitable means for securing the diskupon' the hand of the instance I provide a bracket 7, curved at one end thereof, as shown at 8, said curved portion terminatln in a right angled portion 9, suitably secure as by means of rlvets 10, to a strapll of flexible material, such'as leather, carrying a buckle 12, whereby the strap may be secured around the hand or wrist of the operator.

The bracket 7 is secured, as by means of rivets 13, to the disk 1. By means of the curved portion 8 of the bracket, the d1sk 1 is held spaced from the hand of the operator so that the fingers and hand of the operator will have full play. c p 0 Figure 4 illustrates the foperatmn of my "device, and such operation is apparent from an inspection of this diagrammatic figure.

I am aware, of course, that it is not new to provide a fluorescent surface up on various objects, such as door knobs, electric swltches, push buttons, andupon the chass1s of an automobile, etc, but, so far as I am aware,

manufacture, can be sold more chea ly andis less liable to become broken. lectric light bulbs are easily broken and batteries.

wear out and have to be renewed. Thus an electric signalling device is expensive and not generally used.

, What I claim to be new is:

1. A signal comprising a disk of sheet material, a hand-attaching means carried upon' one side of the disk, fluorescent coating covering the central portion of the disk upon the side opposite the hand-attaching means leaving a nonefiuorescent border, the fluorescent and non-fluorescent surfaces being of contrasting colors.

2. A signal comprlsing a disk of sheet ma- 7 ,terial, a hand-attaching means carried upon one side of the disk, a fluorescent coating covering the central portion of the disk upon the side opposite the hand-attaching means leaving a non-fluorescent border, a flexible transparent sheet coverlng the fluorescent surface said fluorescent and non-fluorescent surfaces'being of contrastmg colors.

In testimony whereof I hereunto affix my signature.
